Abstract: A fixing assembly has a support element adapted to be fixed to a component of a vehicle, and a frame adapted to support an accessory in a fixed relative position and connected to the support element in a fixed position; the support element has two openings which are engaged by respective protruding pins of the frame so as to allow a rotation of the frame towards the support element during a mounting step in which the protruding pins are inserted in the openings; a snap fitting prevents the displacement of the frame at the end of the aforementioned rotation, and then blocking devices, of the screw type, secure the frame in a stable position; the snap fitting has an elastically deformable element which is snap-fitted to a retention shoulder and forms part of a portion made of polymeric or elastomeric material of one between the support element and the frame.

Abstract: In a scrub-clearing tool of the type comprising a tube, a blade supported for rotation at one end of the tube, a motor for driving the blade and transmission shaft for connecting the drive motor to the blade, a disc is provided for protecting the blade and is mounted for rotation on the shaft of the blade with the interposition of a bearing. The protective disc has a diameter larger than the outer diameter of the blade and has a plurality of recesses around its periphery, the inner edges whereof are spaced from the center of the disc by a distance less than the radius of the outer circumference of the blade. The protective disc is normally rotated together with the blade. It stops when it comes into contact with the ground or with some obstacle, while the blade can continue to rotate by virtue of the presence of the bearing.
